Some organisms undergo asexual reproduction through mitosis, while others reproduce sexually, and their cells undergo meiosis to
produce gametes. If there were drastic changes in temperature in an ecosystem, which process do you predict would be most beneficial to a species? Mitosis: it causes genetic mutations, which may be favorable to the species. Meiosis: it increases genetic variation, which helps ensure the species will survive. Meiosis: it produces more daughter cells, which increases the population of the species. Mitosis: it produces identical offspring, which increases genetic variation.
Meiosis: it increases genetic variation, which helps ensure the species will survive.
Explanation:
<em>Crossing over and genetic recombination happen during meiosis and both processes ensure that the daughter cells are genetically variant from the parent cells.</em>
Crossing over and genetic recombination increase the genetic variability of a population and consequently increases their chances of survival in case of changes to the environment.
Many birds, such as geese, seasonally fly to warm places when the weather gets cold. They then return when the weather warms. This process is called migration. ... Migration enables many animals to move to places where it is easier for them to survive.
